The Volvo Penta 280, 280T, and 280PT are powerful and reliable marine sterndrive engines designed for a variety of recreational and commercial boating applications. These gasoline-powered engines are known for their robust construction, efficient performance, and smooth operation, making them a popular choice among boat owners seeking dependable power on the water. The 280 series features a displacement of 4.3 liters (261 cubic inches) and delivers a maximum power output ranging from 200 to 225 horsepower, depending on the specific model and configuration. Key features include a cast-iron block and cylinder heads for durability, a single overhead camshaft design for efficient operation, and a fuel-injected system for reliable starting and smooth running.

The 280T and 280PT models differ from the standard 280 by incorporating turbocharging technology to enhance power and torque output. The turbocharger, located on the exhaust manifold, helps to increase engine efficiency by using exhaust gases to spin a turbine and force more air into the cylinders. This results in a significant boost in horsepower and torque, particularly at low engine speeds. The 280PT model further enhances performance with a propeller shaft that connects directly to the transmission, eliminating the need for a separate drive shaft and reducing power loss. This design improves efficiency and provides smoother running at higher speeds. These engines are commonly found in a variety of boat types, including cruisers, runabouts, and sport boats, offering excellent performance and reliability for a wide range of boating activities.
